ESPECIFICATION forming part of Letters Fatent No. 301,683, dated July 8, 1884.

Application filed Apr-i121, 1584. (No model.)

To all whom it may concern.-

Be it known that l, Gnonon SMILLIE, a citizen of the United States, residing at Xewark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Pin-and-Link Attachments for Draw-Heads; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to lettersof rel? erence marked thereon, which form a part of this specification.

The object of this invention is to facilitate the operation of coupling cars, to prevent the loss of links, and to otherwise improve the construction of the draw-heads.

The invention consists in the arrangements and combinations of parts, substantially as will be hereinafter set forth, and finally embodied in the clauses of the claims.

Referring to the accompanying drawings, in which similar letters of reference indicate like parts in each of the several figures, Figure 1 is a vertical section of a draw-head, showing the same in position prior to coupling. Fig. 2 is a horizontal section through line at, Fig. at, and Fig. 3 isavertical section taken through 3;, same figure. Said Fig. 4 is a vertical section showing the link and pin in engagement for coupling. 7

In carrying out the invention, 1 form the draw-head a. with a springactuated plunger, 6, working in a longitudinal chamber, 0, in said drawhead. Said draw -head is perforated vertically by a pin-receptacle, d, in which the pin e is secured.

Said plunger is adapted to be thrown by the spring f across the perforation when the pin is drawn upward, so that said pin rests onthe top of said plunger. hen the said plunger is thrown backward by engagement with the link, as in Figs. 2 and i, the pin drops through thelink and holds the same firmly in position.

To hold the link out horizontallyor approximately, to enable the same to engage readily with the cooperating draw-head, I form the link wider than the plunger and chamber in which said plunger operates, and laterally adj acent to said plunger in the drawliead I form recesses shown more clearly in Figs. 2 and 3, and hold the same so that said link will remain out horizontally,even though the pressure of the plunger be removed therefrom, or should the pressure of the said plunger be insufficient for the purpose. Said recesses are flaring, substan tially as shown, to allow the link a sufficient vertiealand lateral movement, and to form bearings h for the link, so that when the latter is coupled in the draw-head the said drawhead receives the force of the impact where it has the most strength to resist it. Furthermore, the link, striking the bearings, prevents the spring back of the plunger and other smaller parts in the chamber (2 from being broken. The outer extremity of the drawhead is hopper-shaped, and to the lower edge thereof is pivoted a connective, 75, independent of the usual coupling-pin, to carry the link Z, so that it will be always at hand and cannot be abstracted surreptitiously. Said connective is pivoted between ears on the draw-head, and is provided with a slot, m which allows play to-the link. Said link is provided with a center bar, a, which works in said slot and keeps the connective where it will notinterfere with or hinder the coupling process. The connective is preferably hat, and is so pivoted as to have but one positive pivotal movement, and it is connected to the link near oneend thereof. By this construction the said connective lies, when the parts are coupled, entirely or almost entirely within the line of the edge of the draw -head. \Vhen the cars come together, the link projecting from one of the draw-heads first strikes the flaring or hoppershaped portion thereof, and is guided against the plunger, which is repressed until the pin is allowed to drop. The link then strikes the shoulders or hearings in the recess, and the to receive the sides of the link, as.

head is pressed back until the draw-heads make a contact. The links, therefore, are not required to bear any great pressure, and are prevented from bending or breaking.

Having thus described the invention, what I claim as new is- 1. In combination, in a coupling, a drawhead having a spring-actuatedplunger narrower than the link, and having recesses g g in said head laterally adjacent to said plunger, and a link wider than the plunger, and adapted to have the sides thereof lie in said recesses, the end of said link lying centrallyacross the face of the plunger, said link there by being held horizontally, or approximately so, to engage the co-operating draw-head.

2. In combination with the draw-head and link, the connective 7c, permanently uniting- 5. As an improved article of manufacture, a car-coupling consisting of a draw-head hav- 25 ing a central chamber, 0, and a spring-actuated plunger, 1), working therein and bearing against the end of the link, and having laterally-adj acent bearings or shoulders adapted to receive the link after it has struck the said 0 plunger and partly repressed'the same, to prevent excessive repression, and a link and pin, said linkbeing adapted to strike the plunger and repress the same, and subsequently strike the lateral bearings, all said parts being ar- 5 ranged and operating substantially as set forth.

In testimony that I claim the foregoing Ihave hereunto set my hand this 5th day of April, 1884.
